ハウジングケースと、当該ハウジングケースの製造方法とこれに用いるガ ラスインサート成形用金型  Housing case, method for manufacturing the housing case, and glass insert molding die used therefor
技術分野  Technical field
[0001] 本発明は、小型の電気機器や通信機器のハウジングケースであって、ハウジングケ ースの正面部、特に LCD等の表示画面を覆う部分に充分な硬度を与えることができ るハウジングケースと、当該ハウジングケースの製造方法とこれに用いるガラスインサ ート成形用金型に関する。  [0001] The present invention relates to a housing case for a small electric device or communication device, which can give sufficient hardness to the front portion of the housing case, in particular, a portion covering a display screen such as an LCD. And a method for manufacturing the housing case and a glass insert molding die used therefor.
背景技術  Background art
[0002] 小型の電気機器や通信機器、例えば洋服やカバンの中に保持されて、持ち運びさ れるデジタルオーディオプレーヤーや携帯電話は、誤って落下させてしまったり、力 バンの中の他のものにぶっかったりして、表面に衝撃を受ける場合が多い。  [0002] Digital audio players and mobile phones that are carried in small electric devices and communication devices, such as clothes and bags, may be accidentally dropped or put on other items in a power van. In many cases, the surface is impacted by impact.
[0003] このため、これらの機器のハウジングケースは、耐傷性を高めるためにハウジングケ ースの正面となる部分、特に LCD等の表示画面を覆う部分に高!/、硬度のハードコー ト層を積層する必要がある。例えば特許文献 1には、ベースフィルム上に剥離層、ノ、 ードコート層 103、印刷層、接着層、を順次積層してなり、前記ハードコート層 103は 、ハウジングケース 100の正面となる部分では高硬度とするようにハードコートを積層 し、前記印刷層には非印刷部 102を有する印刷パターンを複数設けた連続フィルム を、ガラスインサート成形用金型内に連続して通過させ、該ガラスインサート成形用金 型内で、前記連続フィルムの接着層側に透明な合成樹脂を射出することにより、前記 連続フィルムを前記ガラスインサート成形用金型のキヤビティ形状に絞りながら合成 樹脂層 101を形成し、該合成樹脂層の硬化後、ハードコート層 103、印刷層、接着 層及び合成樹脂層 101をベースフィルム及び剥離層から取り外してなるハウジングケ ース 100 (図 38参照)が開示されている。なお、図 38中の 104は LCDの表示画面を 覆う表示窓、 105はボタン孔である。  [0003] For this reason, the housing cases of these devices are provided with a hard coat layer of high / hardness on the front surface of the housing case, particularly on the portion covering the display screen such as an LCD, in order to enhance scratch resistance. Need to be stacked. For example, in Patent Document 1, a release layer, a node coat layer 103, a printing layer, and an adhesive layer are sequentially laminated on a base film, and the hard coat layer 103 is high in a portion that is a front surface of the housing case 100. A hard film is laminated so as to have hardness, and a continuous film in which a plurality of printing patterns having non-printing portions 102 are provided on the printing layer is continuously passed through a glass insert molding die, and the glass insert molding is performed. By injecting a transparent synthetic resin into the adhesive layer side of the continuous film in the mold, the synthetic resin layer 101 is formed while the continuous film is squeezed into the cavity shape of the glass insert molding mold, After the synthetic resin layer is cured, the housing case 100 (in which the hard coat layer 103, the printing layer, the adhesive layer, and the synthetic resin layer 101 are removed from the base film and the release layer) 38 reference) is disclosed. In FIG. 38, 104 is a display window covering the LCD display screen, and 105 is a button hole.
[0004] ハードコート層 103は、通常、熱硬化型樹脂、あるいは紫外泉硬化型樹脂等の活 性エネルギー線重合性樹脂をプラスチック基材上に直接、或いは 0. 03-0. 5 μ ΐη 程度のプライマー層を介して 3〜; 10 m程度の薄い塗膜を形成して製造している。 [0004] The hard coat layer 103 is usually formed of a thermosetting resin or an active energy ray polymerizable resin such as an ultraviolet spring curable resin directly on a plastic substrate or 0.03-0. 5 μΐη. It is manufactured by forming a thin film of about 3 to 10 m through a primer layer of about 10 m.
[0005] しかしながら、薄い塗膜からなるハードコート層 103では、ハウジングケースの正面 部分、特に高レ、硬度が要求される LCD等の表示画面を覆う部分の硬さとしては充分 でない。 [0005] However, the hard coat layer 103 made of a thin coating film is not sufficient as the hardness of the front portion of the housing case, particularly the portion covering a display screen such as an LCD or the like that requires high level and hardness.
[0006] したがって、本発明は、上記の課題に鑑みてなされたものであり、ハウジングケース の正面部分、特に LCD等の表示画面を覆う部分に充分な硬度を与えることができる ハウジングケースと、当該ハウジングケースの製造方法とこれに用いるガラスインサー ト成形用金型を提供することを目的とする。  [0006] Therefore, the present invention has been made in view of the above problems, and a housing case capable of giving sufficient hardness to a front portion of a housing case, particularly a portion covering a display screen such as an LCD, and the like, It is an object of the present invention to provide a method for manufacturing a housing case and a glass insert molding die used therefor.

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
[0032] 1.ハウジングケース  [0032] 1. Housing case
以下、図面を用いて本発明の実施の形態について詳細に説明する。  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
図 1に示すハウジングケース 1は、当該ハウジングケース正面の寸法と略同一の寸 法であり少なくともガラス板で構成される平面板 2と、前記平面板 2の裏面周縁部を支 持するように前記平面板に一体化された樹脂枠 3とを備えたものである。なお、図 1中 、(b)は(a)の分解図である。図示しないもう一方のバックケースとともに一体化され、 これらの内側に、各種電子部品を搭載した基板を保持することにより、小型の電気機 器や通信機器が構成される。  The housing case 1 shown in FIG. 1 is substantially the same as the front surface of the housing case and has a flat plate 2 made of at least a glass plate, and the back surface peripheral portion of the flat plate 2 is supported. And a resin frame 3 integrated with a flat plate. In FIG. 1, (b) is an exploded view of (a). It is integrated with the other back case (not shown), and by holding a board on which various electronic components are mounted inside these, a small electric device or communication device is configured.
[0033] 前記平面板 2は、少なくともガラス板で構成され、当該構成によってハウジングケー ス 1の正面部分に充分な硬度(9Η以上)を与えることができる。前記ガラス板としては 、普通板ガラス、強化板ガラス、磨き板ガラスなどを用いることができる。また、前記ガ ラス板の厚みは強度の点から 0. 3mm〜2. Ommとするのが好ましい。より好ましくは 0. 5mm〜2. Omm、 らにヌナまし ほ 0. 8mm〜l . 5mmである。  [0033] The flat plate 2 is composed of at least a glass plate, and this configuration can give sufficient hardness (9 mm or more) to the front portion of the housing case 1. As the glass plate, ordinary plate glass, tempered plate glass, polished plate glass and the like can be used. The thickness of the glass plate is preferably 0.3 mm to 2. Omm from the viewpoint of strength. More preferably, it is 0.5 mm to 2. Omm, and moreover, Nuna Mashou is approximately 0.8 mm to l.5 mm.
[0034] 本発明者は、前記課題を解決するための手段として、最初、従来のハウジングケー スにおいて、ケース正面のハードコート層 103に代えて前記平面板 2を合成樹脂層 に一体化させることを考えていた。すなわち、ケース正面では前記平面板 2と合成樹 脂層 101とが全面的に密着する構成である。し力もながら、射出成形用金型内で成 形された前記合成樹脂層 101は、図 39に示されるように冷却固化時に成形収縮し、 しかも前記平面板 2と全面的に密着してレ、る面側では成形収縮せず、反対面側のみ で成形収縮が進むため(例えば、図 39の矢印方向)、得られたハウジングケース 106 に反りが発生することがあった。そして、前記平面板 2は、反りに耐えられなくなると破 損した。 [0034] As a means for solving the above-mentioned problems, the present inventor first made a conventional housing case. In this case, it was considered to integrate the flat plate 2 into the synthetic resin layer in place of the hard coat layer 103 on the front surface of the case. That is, the flat plate 2 and the synthetic resin layer 101 are in close contact with each other in front of the case. However, the synthetic resin layer 101 formed in the injection mold is molded and shrunk when cooled and solidified as shown in FIG. 39, and is in close contact with the flat plate 2 as shown in FIG. Molding shrinkage progresses only on the opposite surface side (for example, in the direction of the arrow in FIG. 39), and the resulting housing case 106 may be warped. The flat plate 2 was damaged when it could not withstand warping.
[0035] そこで、本発明は、前記平面板 2の裏面のうち周縁部においてのみ一体化させるよ うに、樹脂枠 3とした。例えば、図 1においては、前記樹脂枠 3は前記平面板 2の裏面 周縁部全周を支持している。本発明の樹脂枠 3は前記平面板 2と全面的に密着して いないので、当該樹脂枠 3が冷却固化時に成形収縮しても、その影響は前記平面板 2全面までおよびにくい。したがって、得られたハウジングケースに反りが発生するこ とを防止できる。  Therefore, in the present invention, the resin frame 3 is formed so as to be integrated only at the peripheral edge portion of the back surface of the flat plate 2. For example, in FIG. 1, the resin frame 3 supports the entire periphery of the back surface of the flat plate 2. Since the resin frame 3 of the present invention is not in full contact with the flat plate 2, even if the resin frame 3 is molded and shrunk during cooling and solidification, the influence is not likely to reach the entire flat plate 2. Therefore, it is possible to prevent the obtained housing case from being warped.
[0036] 前記樹脂枠 3としては、ポリスチレン系樹脂、ポリオレフイン系樹脂、 ABS樹脂、 AS 樹脂、 AN樹脂などの汎用樹脂を挙げることができる。また、ポリフエ二レンォキシド' ポリスチレン系樹脂、ポリカーボネート系樹脂、ポリアセタール系樹脂、ポリアクリル系 樹脂、ポリカーボネート変性ポリフエ二レンエーテル樹脂、ポリブチレンテレフタレート 樹脂、ポリブチレンテレフタレート樹脂、超高分子量ポリエチレン樹脂などの汎用ェン ジニアリング樹脂やポリスルホン樹脂、ポリフエ二レンサルファイド系樹脂、ポリフエ二 レンォキシド系樹脂、ポリアリレート樹脂、ポリエーテルイミド樹脂、ポリイミド樹脂、液 晶ポリエステル樹脂、ポリアリル系耐熱樹脂などのスーパーエンジニアリング樹脂を 使用することもできる。とくに成形収縮率 0. 6%以下の物性を持つ樹脂材料を樹脂 枠 3に用いると前記反り防止の点でより好ましぐこのような樹脂材料としては、例えば ポリアクリル系樹脂などが該当する。また、樹脂枠 3は、着色されていても、着色され ていなくてもよい。  [0036] Examples of the resin frame 3 include general-purpose resins such as polystyrene resin, polyolefin resin, ABS resin, AS resin, and AN resin. In addition, general purpose resins such as polyphenylene oxide polystyrene resins, polycarbonate resins, polyacetal resins, polyacrylic resins, polycarbonate-modified polyphenylene ether resins, polybutylene terephthalate resins, polybutylene terephthalate resins, and ultrahigh molecular weight polyethylene resins. Use super engineering resins such as engineering resin, polysulfone resin, polyphenylene sulfide resin, polyphenylene oxide resin, polyarylate resin, polyetherimide resin, polyimide resin, liquid crystal polyester resin, polyallyl heat resistant resin, etc. You can also. In particular, when a resin material having a physical property of a molding shrinkage ratio of 0.6% or less is used for the resin frame 3, such a resin material that is more preferable in terms of preventing the warpage corresponds to, for example, a polyacrylic resin. Further, the resin frame 3 may be colored or may not be colored.
[0037] 前記平面板 2と前記樹脂枠 3との一体化は、次のようにして行なう。まず、可動型と 固定型とからなる成形用金型内に前記平面板 2を送り込み、真空吸引等でキヤビティ 面の所定位置に前記平面板 2を固定し、成形用金型を閉じた後、ゲートより溶融樹 脂をキヤビティ内に射出充満させ、前記樹脂枠 3を形成するのと同時にその樹脂枠 3 に前記平面板 2を接着させる。前記樹脂枠 3を冷却した後、成形用金型を開いて前 記平面板 2と前記樹脂枠 3との一体化物を取り出す。なお、成形用金型が垂直方向 に型開きする縦型の場合、前記平面板 2は真空吸引等を行なわずに固定することも できる。 [0037] The flat plate 2 and the resin frame 3 are integrated as follows. First, the flat plate 2 is fed into a molding die composed of a movable die and a fixed die, and the cavity is sucked by vacuum suction or the like. After the flat plate 2 is fixed at a predetermined position on the surface and the molding die is closed, the molten resin is injected and filled into the cavity from the gate, and at the same time the resin frame 3 is formed, The flat plate 2 is bonded. After the resin frame 3 is cooled, the molding die is opened, and the integrated product of the flat plate 2 and the resin frame 3 is taken out. In the case where the molding die is a vertical type that opens in the vertical direction, the flat plate 2 can be fixed without performing vacuum suction or the like.
[0038] なお、前記平面板 2と前記樹脂枠 3との一体化物は、箱型(図 2〜図 4参照)とするこ ともできるし、蓋型(図 5、図 6参照:破線は対応するバックケース)とすることもできる。 なお図 2は、図 1における II II線断面図であり、図 3〜図 6は図 2の別実施形態であ る。また、箱型、蓋型に関わらず、図 2、図 5及び図 6に示すように前記平面板 2の寸 法がハウジングケース 1正面の寸法より僅かに小さくすれば、図 3及び図 4に示すよう に前記平面板 2の寸法がハウジングケース 1正面の寸法と同一である場合と比較して 、ハウジングケース 1の外観デザイン設計の自由度を増すことができる。例えば、ハウ ジングケース 1の角部に丸みを設けるようなデザインが可能である(図 2、図 5及び図 6 参照)。また、箱型において、図 2及び図 3に示すように箱の側壁の厚みよりも前記平 面板 2と前記樹脂枠 3との一体化幅を大きくすれば、その分だけ前記平面板 2の支持 面積が増加するため、ハウジングケース 1の強度を増すことができる。  [0038] The integrated product of the flat plate 2 and the resin frame 3 can be a box type (see FIGS. 2 to 4) or a lid type (see FIGS. 5 and 6: broken lines correspond). Back case). 2 is a cross-sectional view taken along the line II-II in FIG. 1, and FIGS. 3 to 6 are other embodiments of FIG. Regardless of the box type or the lid type, if the dimension of the flat plate 2 is slightly smaller than the dimension of the front surface of the housing case 1 as shown in FIGS. As shown, the degree of freedom in designing the external appearance of the housing case 1 can be increased as compared with the case where the dimension of the flat plate 2 is the same as the dimension of the front surface of the housing case 1. For example, it is possible to design the housing case 1 to have a rounded corner (see Fig. 2, Fig. 5 and Fig. 6). Further, in the box shape, as shown in FIGS. 2 and 3, if the integrated width of the flat plate 2 and the resin frame 3 is made larger than the thickness of the side wall of the box, the flat plate 2 is supported accordingly. Since the area increases, the strength of the housing case 1 can be increased.
[0039] また、前記平面板 2の裏面周縁部を粗面化しておけば、前記平面板 2と前記樹脂 枠 3との密着力を向上させることができる。  [0039] Further, if the peripheral edge of the back surface of the flat plate 2 is roughened, the adhesion between the flat plate 2 and the resin frame 3 can be improved.
[0040] また、本発明のハウジングケース 1の構成は、上記した態様に限定されるものでは なぐたとえば、前記樹脂枠 3が、前記平面板 2の裏面周縁部のうち;!〜 3辺を支持し てレ、るようにしてもよ!/、し(図 7〜図 10参照)、複数に分割されて前記平面板 2の裏面 周縁部を支持しているようにしてもよい(図 11及び図 12参照)。これらの場合、当該 樹脂枠 3が冷却固化時に成形収縮しても、成形収縮の影響が前記平面板 2全面まで より、およびに《なる。すなわち、樹脂枠 3が前記平面板 2の裏面周縁部全周を支持 する場合と比べて、ハウジングケースの反り防止効果が向上する。また、樹脂枠 3が 前記平面板 2の裏面周縁部全周を支持しない場合、ハウジングケース 1の側面に入 出力端子などを設け易い。 [0041] また、前記平面板 2が、前記ガラス板の裏面に加飾が施されたものであってもよい( 図示せず)。前記ガラス板は充分な硬度(9H以上)を有しているため傷付きにくぐ当 該ガラス板を通して視認される裏面の加飾はその美しさが損なわれることはない。 [0040] Further, the configuration of the housing case 1 of the present invention is not limited to the above-described embodiment. For example, the resin frame 3 supports the! Then, it may be made! /, (See FIGS. 7 to 10), and may be divided into a plurality of parts to support the peripheral edge of the back surface of the flat plate 2 (see FIGS. 11 and 11). (See Figure 12). In these cases, even if the resin frame 3 undergoes molding shrinkage at the time of cooling and solidification, the influence of molding shrinkage is from the entire surface of the flat plate 2 and to <<. That is, the warp prevention effect of the housing case is improved as compared with the case where the resin frame 3 supports the entire periphery of the back surface peripheral edge portion of the flat plate 2. In addition, when the resin frame 3 does not support the entire periphery of the rear peripheral edge of the flat plate 2, it is easy to provide input / output terminals and the like on the side surface of the housing case 1. [0041] Further, the flat plate 2 may be one in which the back surface of the glass plate is decorated (not shown). Since the glass plate has sufficient hardness (9H or more), the beauty of the decoration on the back surface that is visually recognized through the glass plate is not impaired.
[0042] 前記ガラス板の裏面への加飾は、加飾層を印刷形成することによって施すと好適で ある。加飾層の材質としては、ポリ塩化ビュル系樹脂、ポリアミド系樹脂、ポリエステル 系樹脂、ポリアクリル系樹脂、ポリウレタン系樹脂、ポリビュルァセタール系樹脂、ポリ エステルウレタン系樹脂、セルロースエステル系樹脂、アルキド樹脂などの樹脂をバ インダ一とし、適切な色の顔料または染料を着色剤として含有する着色インキを用い ると好適である。印刷方法としては、スクリーン印刷法などを用いると好適である。また 、単色ベタの場合には、スプレーコート法などの各種コート法を採用することもできる  [0042] The decoration on the back surface of the glass plate is preferably performed by printing a decorative layer. The decorative layer is made of polychlorinated bur resin, polyamide resin, polyester resin, polyacrylic resin, polyurethane resin, polybulassal resin, polyester urethane resin, cellulose ester resin, alkyd. It is preferable to use a colored ink containing a resin or the like as a binder and containing a pigment or dye of an appropriate color as a colorant. A screen printing method or the like is preferably used as the printing method. Moreover, in the case of a single color solid, various coating methods such as a spray coating method can be adopted.
[0043] また、加飾層は、金属薄膜層からなるもの、あるいは印刷層と金属薄膜層との組み 合わせからなるものでもよい。金属薄膜層は、加飾層として金属光沢を表現するため のものであり、真空蒸着法、スパッターリング法、イオンプレーティング法、鍍金法など で形成する。この場合、表現したい金属光沢色に応じて、アルミニウム、ニッケル、金 、白金、クロム、鉄、銅、スズ、インジウム、銀、チタニウム、鉛、亜鉛などの金属、これ らの合金又は化合物を使用する。部分的な金属薄膜層を形成する場合の一例として は、金属薄膜層を必要としない部分に溶剤可溶性樹脂層を形成した後、その上に全 面的に金属薄膜を形成し、溶剤洗浄を行って溶剤可溶性樹脂層と共に不要な金属 薄膜を除去する方法がある。この場合によく用いられる溶剤は、水又は水溶液である 。また、別の一例としては、全面的に金属薄膜を形成し、次に金属薄膜を残しておき たい部分にレジスト層を形成し、酸又はアルカリでエッチングを行い、レジスト層を除 去する方法がある。 [0043] The decorative layer may be a metal thin film layer or a combination of a printed layer and a metal thin film layer. The metal thin film layer is used to express metallic luster as a decorative layer, and is formed by a vacuum deposition method, a sputtering method, an ion plating method, a plating method, or the like. In this case, use metal such as aluminum, nickel, gold, platinum, chromium, iron, copper, tin, indium, silver, titanium, lead, zinc, alloys or compounds of these depending on the metallic luster color to be expressed. . As an example of forming a partial metal thin film layer, a solvent-soluble resin layer is formed in a portion where the metal thin film layer is not required, and then a metal thin film is formed on the entire surface and then solvent cleaning is performed. There is a method to remove unnecessary metal thin films together with solvent-soluble resin layers. A solvent often used in this case is water or an aqueous solution. Another example is a method in which a metal thin film is formed over the entire surface, and then a resist layer is formed on a portion where the metal thin film is to be left, and etching is performed with acid or alkali to remove the resist layer. is there.

The back side may be decorated (see FIG. 13). In Fig. 13, (b) is an exploded view of (a), 2Α indicates a decorated part and 2Β indicates a non-decorated part. When the surface of the glass plate is decorated, the glass plate has sufficient hardness (9 mm or more). Therefore, the visibility of the display screen of the display device that is visually recognized through the glass plate in the non-decorated portion 2B that is not easily damaged is not impaired. In addition, when the back surface of the glass plate is decorated, the glass plate has sufficient hardness (9H or more), and therefore, the surface of the glass plate is decorated with little damage. As with the case of the display, not only is the display screen easy to see! /, But also the decorative part 2A! / It will not be.

For example, in FIG. 26, FIG. 33, and FIG. 35, the resin frame 3 is the entire back surface peripheral portion of the flat plate 2, and in FIGS. 29 and 30, the resin frame 3 is the back surface peripheral portion of the flat plate 2. Some of them are notched! /, Almost support C-shaped parts! /, Ru. Since the resin frame 3 of the present invention is not in intimate contact with the flat plate 2, even if the resin frame 3 is molded and shrunk during cooling and solidification, the influence is difficult to reach the entire flat plate 2. Therefore, it is possible to prevent the obtained housing case from being warped.
[0056] また、本発明は、前記平面板 2の端面を前記樹脂枠 3が覆っているので、製品の使 用時に前記平面板 2の端面が何かに引っ掛かって前記平面板 2と前記樹脂枠 3の剥 離するおそれがない。  [0056] Further, in the present invention, since the resin frame 3 covers the end surface of the flat plate 2, the end surface of the flat plate 2 is caught by something when the product is used, and the flat plate 2 and the resin There is no risk of peeling frame 3.

A mold that forms a cavity facing the peripheral surface of the flat plate 2 and the end surface of the flat plate 2, wherein the fixed die 15 contacts the peripheral surface of the flat plate 2 facing the fixed die 15. A slide core 5 having a tip (hereinafter referred to as a tip wall portion 5a) and a wall portion (hereinafter referred to as a tip wall portion 5a) that contacts the end bottom surface 5b of the flat plate 2 so as to be positionable. A suction hole 8 is provided in a surface (hereinafter referred to as a flat plate contact surface 7) for sandwiching the flat plate 2 (see FIGS. 18 and 19). Here, FIG. 19 is a cross-sectional view taken along line XIX-XIX in FIG.
[0059] 前記スライドコア 5は、図示しない駆動部により、前記先端底部 5bを前記固定型 15 の前記平面板 2を挟持する面より突出させず且つ前記先端壁部 5bを前記平面板 2と 接触させる平面板位置決め位置 1 (図 19、図 21及び図 22参照)と、前記先端底部 5a 及び前記先端壁部 5bを共に前記平面板 2と離間させるキヤビティ形成位置 Π (図 23、 図 24参照)との間を、型締め方向に進退可能である。また、スライドコア 5は、必要に 応じて前記先端底部 5aを前記固定型 15の前記平面板当接面 7より突出させるガラ スインサート成形品押出し位置 III (図 25参照)まで前進可能とすることができる。 [0059] The slide core 5 is configured such that the tip bottom 5b is fixed to the fixed mold 15 by a drive unit (not shown).

A groove 14 may be formed (see FIG. 34). In this case, the area of the resin frame 3 integrated with the peripheral edge of the back surface of the flat plate 2 is increased by the amount that is filled in the groove portion 14 during molding. As for the flat plate positioning position I, the tip bottom portion 5b may be aligned with the flat plate contact surface 7 of the fixed mold 15 as shown in FIGS. Since the positioning is possible if the portion 5b can be brought into contact with the end surface of the flat plate 2, the tip bottom portion 5b may be retracted from the flat plate contact surface 7 of the fixed die 15.
[0061] 前記平面板 2の端面に位置決め可能に接触する前記先端壁部 5aとは、金型パー ティング面 6に垂直な方向から見た場合に、例えば図 18に示すような対向する 2つの コ字状とすること力できる。もちろん、この実施態様に限定されるものではなぐ前記 平面板 2の形状に応じて前記平面板 2が位置ずれしないような配置を適宜決定すれ ばよぐ例えば、平面板 2の各コーナーに前記先端壁部 5aを配置したり、平面板 2の 各辺の一部に前記先端壁部 5aを配置したりするなどできる。前記平面板 2の形状と しては、図 18に示すような角に丸みを帯びた矩形の他、角に丸みのない矩形、楕円 形状など自由である。また、前記スライドコア 5の数も限定されない。さらには、前記ス ライドコア 5は、図 18のように前記平面板 2の全周に対して部分的に設けてもよいし、 前記平面板 2の全周を前記先端壁部 5aで完全に囲ってもよい。  [0061] The tip wall portion 5a that contacts the end face of the flat plate 2 so as to be positionable is, for example, two opposing faces as shown in FIG. 18 when viewed from a direction perpendicular to the mold parting surface 6. Can be U-shaped. Of course, the present invention is not limited to this embodiment. It is only necessary to appropriately determine an arrangement so that the flat plate 2 is not displaced in accordance with the shape of the flat plate 2. The wall 5a can be arranged, or the tip wall 5a can be arranged on a part of each side of the flat plate 2. The shape of the flat plate 2 is not limited to a rectangle with rounded corners as shown in FIG. 18, but a rectangle with no rounded corners or an elliptical shape. Further, the number of the slide cores 5 is not limited. Furthermore, the slide core 5 may be provided partially with respect to the entire periphery of the flat plate 2 as shown in FIG. 18, or the entire periphery of the flat plate 2 is completely surrounded by the tip wall portion 5a.

(See Figure 22). It should be noted that means other than air suction may be used for adsorbing and fixing the flat plate. For example, a suction cup may be provided on the surface sandwiching the flat plate 2.
[0065] さらに、可動型 10を前記平面板 2を吸着した前記固定型 15に向かって前進移動さ せ型締めし、前記可動型 10と前記固定型 15の前記平面板当接面 7との間に前記平 面板 2を挟持するとともに、前記固定型 15と前記可動型 10と前記平面板 2とにより金 型空間であるキヤビティ 13を形成する(図 23参照)。ここで、前記スライドコア 5は、図 示しない駆動部により、前記先端底部 5bが前記平面板 2の裏面周縁部と所定の距 離だけ離間する位置まで後退移動して、前記スライドコア 5の前記先端壁部 5a及び 前記先端底部 5bと今まで接して!/、た部分まで溶融樹脂の充填を可能として!/、る (キ ャビティ形成位置 11)。なお、前記スライドコア 5の後退移動は、前記可動型 10の前進 移動開始直前、前進移動中、前進移動完了直後のいずれのタイミングでおこなって あよい。  Further, the movable mold 10 is moved forwardly toward the fixed mold 15 that adsorbs the flat plate 2 and clamped, and the movable mold 10 and the flat plate contact surface 7 of the fixed mold 15 are fixed. The flat plate 2 is sandwiched therebetween, and the fixed mold 15, the movable mold 10, and the flat plate 2 form a cavity 13 that is a mold space (see FIG. 23). Here, the slide core 5 is moved backward by a driving unit (not shown) to a position where the tip bottom 5b is separated from the rear peripheral edge of the flat plate 2 by a predetermined distance, and the slide core 5 The tip wall portion 5a and the tip bottom portion 5b are in contact with each other until now, and the molten resin can be filled up to that portion (cavity forming position 11). The backward movement of the slide core 5 may be performed at any timing immediately before the start of forward movement of the movable mold 10, during forward movement, or immediately after completion of forward movement.
[0066] その後に、前記スライドコア 5を前記キヤビティ形成位置 IIに移動させた状態で、ゲ ート 11を通じて射出した溶融樹脂を前記キヤビティ 13内に充填することにより、前記 樹脂枠 3が、前記平面板 2の裏面周縁部を支持し且つ前記平面板 2の端面のうち少 なくとも当該支持部分に連続する部分を被覆するように前記平面板 2に一体化され、 ガラスインサート成形品である前記ハウジングケース 1が得られる(図 24参照)。  [0066] After that, the resin frame 3 is filled with the molten resin injected through the gate 11 in the state where the slide core 5 is moved to the cavity forming position II. The glass plate molded product is a glass insert molded product, which is integrated with the flat plate 2 so as to support the peripheral edge of the back surface of the flat plate 2 and to cover at least a portion of the end surface of the flat plate 2 continuous to the support portion. Housing case 1 is obtained (see Fig. 24).
[0067] 前記溶融樹脂の材料としては、ポリスチレン系樹脂、ポリオレフイン系樹脂、 ABS樹 脂、 AS樹脂、 AN樹脂などの汎用樹脂を挙げることができる。また、ポリフエ二レンォ キシド '·ポリスチレン系樹脂、ポリカーボネート系樹脂、ポリアセタール系樹脂、ポリア クリル系樹脂、ポリカーボネート変性ポリフエ二レンエーテル樹脂、ポリブチレンテレフ タレート樹脂、ポリブチレンテレフタレート樹脂、超高分子量ポリエチレン樹脂などの 汎用エンジニアリング樹脂やポリスルホン樹脂、ポリフエ二レンサルファイド系樹脂、 ポリフエ二レンォキシド系樹脂、ポリアリレート樹脂、ポリエーテルイミド樹脂、ポリイミド 樹脂、液晶ポリエステル樹脂、ポリアリル系耐熱樹脂などのスーパーエンジニアリング 樹脂を使用することもできる。とくに成形収縮率 0. 6%以下の物性を持つ樹脂材料を 樹脂枠 3に用いると前記反り防止の点でより好ましぐ例えばポリアクリル系樹脂など である。また、樹脂枠 3は、着色されていても、着色されていなくてもよい。 [0067] Examples of the material of the molten resin include general-purpose resins such as polystyrene resin, polyolefin resin, ABS resin, AS resin, and AN resin. In addition, polyphenylene oxide, polystyrene resin, polycarbonate resin, polyacetal resin, polyacrylic resin, polycarbonate-modified polyphenylene ether resin, polybutylene terephthalate resin, polybutylene terephthalate resin, ultrahigh molecular weight polyethylene resin, etc. Super engineering such as general-purpose engineering resin, polysulfone resin, polyphenylene sulfide resin, polyphenylene oxide resin, polyarylate resin, polyetherimide resin, polyimide resin, liquid crystal polyester resin, polyallyl heat resistant resin Resin can also be used. In particular, when a resin material having a physical property of a molding shrinkage rate of 0.6% or less is used for the resin frame 3, it is more preferable in terms of preventing the warp, such as polyacrylic resin. Further, the resin frame 3 may be colored or may not be colored.
[0068] そして、前記可動型 10を前記固定型 15から離間するように後退移動、すなわち型 開きした後、前記スライドコア 5を前記駆動部により前記ガラスインサ一ト成形品押出 し位置 IIIに前進移動させる(図 25参照)。これにより、スライドコア 5がェジェクターピ ンの役割を果たし、ハウジングケース 1は固定型 15から良好に引離されることになり、 この金型装置から容易に取り外すことが可能になる。なお、別に専用のェジェクタ一 ピンが存在する場合は、前記スライドコア 5によってガラスインサート成形品押出しを fiなわなくてもよい。 Then, after the movable mold 10 is moved backward so as to be separated from the fixed mold 15, that is, the mold is opened, the slide core 5 is advanced to the glass insert molded product extrusion position III by the drive unit. Move it (see Figure 25). As a result, the slide core 5 serves as an ejector pin, and the housing case 1 is satisfactorily separated from the fixed mold 15 and can be easily removed from the mold apparatus. If there is another dedicated ejector pin, it is not necessary to push the glass insert molded product through the slide core 5.
[0069] 上述のように、本実施形態による前記ガラスインサート成形用金型を用いたハウジ ングケースの製造方法によれば、スライドコア 5が、裏面周縁部を支持する樹脂枠 3を 成形するためのキヤビティを形成するのみならず、平面板 2の位置決め機構、さらに 必要に応じてガラスインサート成形品の押出し機構を兼ねるため、ハウジングケース 1の製造が低コストで容易に行える。  [0069] As described above, according to the housing case manufacturing method using the glass insert molding die according to the present embodiment, the slide core 5 forms the resin frame 3 that supports the peripheral edge of the back surface. The housing case 1 can be easily manufactured at low cost because it also serves as a positioning mechanism for the flat plate 2 and, if necessary, an extrusion mechanism for the glass insert molded product.
[0070] なお、前記平面板 2と前記樹脂枠 3との一体化物は、蓋型(図 26、図 29及び図 30 参照)とすることもできるし、箱型(図 33、図 35参照)とすることもできる。なお、図 26 ( c)及び(d)は、夫々図 26 (b)における XXVIc— XXVIc断面図、 XXVId— XXVId断 面図である。また、図 29 (c)及び(d)は、夫々図 29 (b)における XXIXc— XXIXc断 面図、 XXIXd— XXIXd断面図であり、図 30 (c)及び(d)は、夫々図 30 (b)における XXXc— XXXc断面図、 XXXd— XXXd断面図である。また、箱型とする場合でも、 図 33に示すようにスライドコア 5の外側に箱の側壁用のキヤビティを形成するタイプや 、図 35に示すようにスライドコア 5の後退により側壁用のキヤビティを形成するタイプ が考えられる。図 33及び図 35も上記と同様に、図 33 (c)及び(d)は、夫々図 33 (b) における XXXIIIc— XXXIIc断面図、 XXXIId— XXXIId断面図であり、図 35 (c)及 び(d)は、夫々図 35 (b)における XXXVc— XXXVc断面図、 XXXVd— XXXVd断 面図である。  [0070] The integrated body of the flat plate 2 and the resin frame 3 can be a lid type (see Figs. 26, 29 and 30) or a box type (see Figs. 33 and 35). It can also be. FIGS. 26 (c) and (d) are XXVIc-XXVIc cross-sectional view and XXVId-XXVId cross-sectional view, respectively, in FIG. 26 (b).

As an example of forming a partial metal thin film layer, a solvent-soluble resin layer is formed on a portion where the metal thin film layer is not required, and then the whole is formed thereon. There is a method in which a metal thin film is formed on the surface, and the unnecessary metal thin film is removed together with the solvent-soluble resin layer by solvent cleaning. A solvent often used in this case is water or an aqueous solution. Another example is a method in which a metal thin film is formed over the entire surface, and then a resist layer is formed on a portion where the metal thin film is to be left, and etching is performed with acid or alkali to remove the resist layer. is there.
